Amnesia Haze, bred in the Netherlands in the 1990s by Hy-Pro Seeds under the name “Amnesia”, goes by many other monikers. Whether you know her as the original Amnesia, Amnesia Haze, Champagne Haze, The Bomb, Ultra Haze, or by another name entirely—one thing everyone can agree on is the sheer potency of this sativa-dominant strain.

The biggest downside of sativas like Amnesia is that they can take quite a while to flower. 12 weeks is the average, but some phenotypes have been known to take a whopping 20 weeks to finish bloom! This is simply too long for most home-growers. Furthermore, she can grow quite tall; this is another issue that indoor growers, in particular, aren’t able to accommodate.

In comes Amnesia Haze Automatic to solve these problems. Offering the same euphoric high and spicy, sweet taste as the original Amnesia, but with a much-reduced grow time and a smaller height, this auto strain can be grown by novice and experienced cultivators alike.


Indoors, she will take around 80–85 days to mature from seed to bud. In this time, she can grow quite large for an auto, reaching heights between 80–150cm. This is a clear indication of her sativa genetics—tall plants, large, thin leaves, and long buds.

Much like the original Amnesia, Amnesia Haze Automatic grows vigorously and offers generous yields of hazey, high-quality flowers. Producing up to 180g/plant outside and 400g/m² indoors, she is certainly on the more productive end of the spectrum for an auto. She likes to be fed well, but be careful not to overfeed her as Haze varieties are generally sensitive to nutrients.

Amnesia Haze Automatic’s long, foxtail-like buds waft an earthy and citrusy aroma that only improves once buds are cured. All in all, she has the classic Amnesia aroma, flavor, and effect, but is much more realistic to grow for the average home-cultivator.

    Title : Awesome!
    Comment : Very fast germination (16h in cotton balls). Two babies growing up nice so far. Mostly the plants are outside under sunlight but in case of bad weather I move them inside under 300W LED full spectrum lamp. After 5 weeks they are 40cm tall, flowers are coming from everywhere and they stink a lot, of in a good way. Side branches are also started to stretch out. Ordered blooming adds to give them some extra nutrients. I would recommend this strain. Can't wait to see final results of my first grow. Peace!

    Title : One of the easiest more reliable seeds I had
    Comment : Got 3, germinated, using the paper towel, within less than 10 hours already germinated nicely, and in 3 days they have grown, outdoors using nice bat guano mix substrate, and have not had yet any problems. Do recommend them, they are not the cheapest seeds around, but they are reliable.

Can you grow outdoors???

Royal Queen Seeds Team

All our seeds can be used either for indoor or outdoor growing. However, if using them for outdoor you need to make sure that you are planting when the growing season starts in your area.

Hello friends from Royal Queens, it would be nice if you could tell us what is the CBD content of this strain. Thanks in advance.

Royal Queen Seeds Team

We do not give specific percentage of CBD content on our strains to avoid misinterpretations. The CBD content partially depends on the grow environment, feeding schedule and some other factors. That is why it is hard to say specifically what level a grower should expect.

Hallo Die 150 gr opbrengst . Is dat als de plant binnen of buiten groeit? En indien binnen met een lamp?
